2002 Gmc Sierra 2500hd Crew Cab - front Axle - Photo 08

The front axle is a ball-joint Dana 60 from a Super Duty stuffed with 5.13 gears and an ARB Air Locker. The ball-joint, unit-bearing design of this axle has proven to be a weak link, as several broken hubs and stub shafts can attest. With 360 lb-ft of torque, 39-inch tires, and 7,000 pounds of American iron, something has to give.
